Worm gear telescopic butterfly valve uses and characteristics

The telescopic butterfly valve is suitable for regulating flow and intercepting media in food, pharmaceutical, chemical, petroleum, electric power, textile, papermaking and other water supply, drainage, and gas pipelines with temperatures ≤80°C and nominal pressures ≤1.6MPa. It has the function of compensating for thermal expansion of pipelines. Cold shrink function. Its main features are as follows:

1. Novel and reasonable design, unique structure, light weight, easy to operate, and quick to open and close;

2. In addition to regulating and shutting off, and compensating for thermal expansion and contraction caused by temperature differences in pipelines, telescopic butterfly valves can also facilitate installation, replacement, and difficult-to-repair valves;

3. The sealing part can be adjusted and replaced, and the sealing performance is reliable.
